Under transport safety regulations, what should a driver do when entering an urban roadway tunnel?

1. Turn off all lights and drive in the dark to test night vision
2. Turn on low-beam headlights in advance, strictly observe the reduced tunnel speed limit, maintain safe following distance, and do NOT change lanes or overtake inside the tunnel (隧道内严禁变道超车)
3. Overtake multiple vehicles aggressively on solid white lines
4. Stop in the middle of the tunnel lane to take photos of tunnel architecture
